webView:authenticationChallenge:shouldAllowDeprecatedTLS: Usage

I did not see webView:authenticationChallenge:shouldAllowDeprecatedTLS: (WKNavigationDelegate) mentioned in the session. I have two questions about how to use this API:
  1. What versions of TLS does WebKit define as deprecated?

  2. If an app is compliant with App Transport Security, is this method even called?

Accepted Reply

TLS 1.0 and 1.1 are deprecated (as *all* browser engines agreed, actually)

It is still called even with ATS.
